Tec Help. Boat Classification

[hlb]

Debs barge is for sale. It's Cat D. A bloke is looking to buy it, but wants to change it to Cat C. So whats the difference and what needs doing. Or is there a web site, I cant find one.

Personally I cant think it makes a blind bit of difference. It's still the same boat!! But anyway

You will find what you want HERE
from which I quote.......

Category C - Inshore: Designed for voyages in coastal waters, large bays, estuaries, lakes and rivers where conditions up to, and including, wind force 6 and significant wave heights up to, and including, 2m may be experienced.

Category D - Sheltered: Designed for voyages on small lakes, rivers and canals where conditions up to, and including, wind force 4 and significant wave heights up to, and including, 0.5m may be experienced.

That doesnt tell you how to go about getting a vessel re-categorised which I suspect may be a lengthy and expensive process.....but then you knew that, didnt you /forums/images/graemlins/smile.gif

Design Categories Category Significant Wave Height Beaufort
A - Ocean Exceeding 4m Exceeding 8
B - Offshore Up to & including 4m Up to & including 8
C - Inshore Up to & including 2 Up to & including 6
D - Sheltered Up to & including 0.5m Up to & including 4

Yes darlings, I know what cat A B C D means. But I dont know what makes them C or D. Well apart from, I would not take the barge to sea!! But then, thats not my problem!!

I thought your question was well written - just proves that everyone sees what they want see.!!

Just a guess but I suspect it has more to do with Boat size, shape, hull shape, weight etc and so there may be nothing that can be changed. I doubt is has much to do with accessories i.e have you got an anchor or a long rope or six liftjackets.

Thouhgt it might require the removal of all flowerpots and other canal thingies but there again I saw a canal boat going across the channel bedecked with flowers et al.

Oh do stop beinga Lancashire lummox Haydn and start thinking like a normal person.
As the RYA page I pointed you to says ....."Boats in each category must be designed and constructed to withstand these parameters in respect of stability, buoyancy, and other relevant essential requirements."

So debs boat was 'designed and constructed' to be Category D....NOT category C.
What would need to be done to make it category C compliant? I dunno....you obviously dunno......so you need to find someone who does.....and I doubt very much that that will happen on here on a sunday afternoon.
Whats happening to you man? Time was you'd have told the guy that wants it to be summat its not thats thats the ways its wotsists dangle and to either buy it or sod off so you can get on with summat else........

Just to make the point even stronger......DESIGNED AND CONSTRUCTED it says.....not fitted out you notice but DESIGNED AND CONSTRUCTED !!!

Download the RSG guidelines (and while you're at it the directive with comments combined and the list of notified bodies) from
http://europa.eu.int/comm/enterprise/mar...SG%20Guidelines

A large part is common to all categories ( rules of builders plate and identification, for instance). Things that will have to changed or to be looked into are:
- stability and freeboard, according to ISO 12217-1:2001. Note that compliance with EN ISO 12217 - Stability and Buoyancy assumes compliance with EN
ISO 14946:2001 - Maximum load capacity, EN ISO 11812:2001 - Watertight and quick draining cockpits and EN ISO 12216:2002 - Windows, portlights, hatches, deadlights and doors - Strength and tightness requirements, where relevant.

Concerning the certification:
I hope the boat is less than 12 meters ? If it is longer than 12 meters, you will need an extensive classification from a notified body. If the boat is less then 12m: two more options:
1) the boat can comply with the ISO 12217 Stability and bouyancy standard: you can reclassify the boat without involment from a third party
2) If the boat cannot comply to ISO 12217 :
you need to perform one or more of the following tests, equivalent calculation or control:
- test of stability according to point 3.2 of the Essential Requirements,
- test of buoyancy characteristics according to point 3.3 of the Essential Requirements
These tests or calculations or control shall be carried out on the responsibility of a notified body chosen by the manufacturer.

In Ireland the Irish sailing association was smart enough to request accreditation to become a notified body. The RYA was so engrossed in fighting the RCD that they missed out on the opportunity, much to the detrement of UK boaters.
So in your neck of the woods, it'll be
Human Performance Improvements LtdCulham Science Centre
Culham Innovation Centre
D5
Abingdon
Oxfordshire OX14 3DB
United Kingdom
that's the closest by. But ask pricequotes from other EU notified bodies as well. Some have affiliates in the UK.

now that was a reply.

Delft is, I think, around 15 metres long so you can forget the provisions for boats under 12 metres.
